The localized deformation like a slip line has been researched by many experiment. But the numerical analyses result in wrong predictions of localized deformation patterns and their development. So non-coaxial model is one of the most excellent model of localized deformation prediction. In this study the effect of the average stress is included in the non-coaxial model. And the two effect are figured out for the important factor of localized deformation.
